Tomkins and his team reconstructed an unusual rise in the number of meteorite impacts known as the Ordovician impact spike, ...

Impact craters found around the Earth that were made around the same time could be linked to debris falling from a ring, a new study suggests.

In a discovery that challenges our understanding of Earth's ancient history, researchers have found evidence suggesting that Earth may have had a ring system that formed around 466 million years ago, ...

A recent study claims that Earth may have once had a ring. The theory would explain the presence of an odd density of impact craters around the equator dating back to the Ordovician period.

Earth may have had a ring made up of a broken asteroid over 400 million years ago, a study finds. The Saturn-like feature could explain a climate shift at the time.

"Over millions of years, material from this ring gradually fell to Earth, creating the spike in meteorite impacts," said researcher Andy Tomkins.

Did Earth Really Once Have a Ring Around it? According to One Theory, Yes — And It Left A Mark 21 craters in ancient rock layers are all that's left of Earth's once flashy accesory.

During the Ordovician Period, a time of significant changes for Earth’s life-forms, plate tectonics and climate, the planet experienced a peak in meteorite strikes. Nearly two dozen impact ...

But Earth itself would have been a lot gaudier—decorated with a ring system similar to the ones that circle Jupiter, Saturn, Uranus, and Neptune.

A large asteroid broken apart by Earth's gravitational pull could have formed a Saturn-like ring around the planet about 466 million years ago, a new study found.

During the Ordovician Period, a time of significant changes for Earth’s life-forms, plate tectonics and climate, the planet experienced a peak in meteorite strikes. Nearly two dozen impact ...
